AppIication filed March 22, 1919. Serial No. 284,272.

To all whom it may concern Be it known that I, Oscan Armor, a citizen ofRussia, residing at Detroit in the county of Wayne and State ofMichigan, have invented certain new and useful Tmprovements inJar-Openers; and I do hereby declare the following to be a full, clear,and exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same.

This invention relates to jar openers and the primary object of theinvention is to provide an improved tool for removing the caps fromfruit jars and the like, in a convenient and expeditious manner.

Another object of the invention is to provide an improved jar opener,which can be readily adjusted to fit various sized and so constructed'asto obtain a firm grip on the jar'cap so that the same can be readilyunthreaded from the jar neck and thus eliminate the usual inconveniencesassociated with the opening of Mason and ball jars and otherreceptacles.

A still further object of the invention is to provide an improved jarwrench of the above character, which is durable and efficient in use,one that is simple and easy to manufacture, andone that can be placedupon the market at a reasonable cost.

With these and other objects in view, the invention consists in thenovel construction, arrangement and formation of parts, as will behereinafter more specifically described, claimed and illustrated in theaccompanying drawings, forming a part thereof, in which:

Figure 1 is a plan view of the improved jar opener showing the same inoperative position on a jar.

Fig. 2 is a horizontal longitudinal section through the improved jaropener, and

Fig. 3 is a detail perspective view of the plate removed from thehandle.

Referring. to the drawings in detail, wherein similar referencecharacters designate corresponding parts throughout the several views,the numeral 1 generally indicates the improved jar wrench or opener,which includes a handle 2 formed of wood or the like, which has theouter end thereof rounded, as at 8, for a purpose which will hereinaftermore fully appear. The handle 2 is of substantially flat rectangularconfiguration and has one side edge thereof at the curved end thereofcut away as at 4 to provide a seat for the bracket or strap-bind- 1ngmember 5. l

The metallic bracket 5 consists of fiat base plate 6 having formed onthe side edges thereof at the forward portion of the same upstandingapertured ears 7, which receive the rounded bar 8, the terminals ofwhich are extended through the apertures in the ears and upset, asclearly shown in Fig. 3 of the drawings. The rounded bar 8 is spacedfrom the base plate 6 and forms means for receiving the flexible strap 9and adjustably holding the same in position. The rear end of the baseplate is provided with a downwardly extending tooth 10 which is adaptedto bite into the handle, when the same is placed in operative position.

As stated, the metallic bracket is placed on the cut-out portion 4 ofthe handle with the rear portion thereof in engagement with the shoulderformed by the cut-out portion. One end of the flexible strap 9, which ispreferably formed from canvas or other heavy fabric, is placed betweenthe handle and the base plate 5 of the metallic bracket and the tooth 10extends therethrough. The base plate is provided with an aperture 16which registers with a corresponding aperture formed in the handle and arivet or other suitable fastening means 18 is extended through theregistering apertures and the fabric strap 9 and firmly clamps themetallic bracket and strap in position on the handle.

The flexible strap 9 is then looped over the base plate and is insertedbetween the rounded bar 8 and the base plate and the free end thereof isbrought back and insorted between the bar 8 and the base plate. Thisforms a closed loop 19 which is adapted to engage the outer surface of ajar cap. In operation of the improved device, the loop 19 is placedaround the jar cap and the free end of the strap is pulled until thesame is adjusted to the cap. The handle 2 is then turned and the roundedend thereof engages the strap which effectively binds the same betweenthe base plate and the bar 8 and holds the strap against movement. Uponfurther movement of the handle, which forms a lever, the rounded endforming a fulcrum therefor, the strap is drawn taut and firmly grips thejar, and thus the cap is readily unthreaded upon further movement of thehandle. When it is desired to thread the cap on the jar neck, theposition of the device is reversed and the handle is rotatedin theopposite direction.

From the foregoing description it can be seen that an improved jarwrench is provided, by means of which a tight gripis obtained l pon thej ar cap, whereby "the same map; be effectively removed from the ar.

hat I claim as new is:

A jar opener comprising a lever, a plate monntfedthereon at a :pointbetween the ends thereof and carrying at one end a bar which is spacedfrom the intermediate portion of the plate and at its other end a toothwhich is embedded in the material of which the lever vis composed, astrap having one end portion inserted between the plate and the leverand the securing device passing transversely through the plate strap andlever.

In testimony whereof 1i affix my signature in presence of two witnesses.
